REVERSIBLE IPIVO'IEID WINDOW.

Specification of Letters Patent.

Application filed April 10, 1911.

Patented Dec. 26, 1911.

Serial No. 619,957.

To all whom it may concern:

Be it known that I, CHARLES B. Pos'r, a citizen of the United States, and resident of New London, in the county of Huron and 'State of Ohio, have invented certain new and useful Improvements in Reversible Pivoted Windows, of which I hereby declare the following to be a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.

The objects of the invention are to provide an improved form of reversible window in which the meeting edges of the sliding and rotatable portions are protected by spring metal strips which are so arranged and constructed as to overlap as the rotatable window sash is raised to the vertical position and by their tension to bind the parts tightly together, so as to prevent the sash from rotating and also to afford suflicient frictional resistance to hold the sash steadily when it is placed in the vertical position and to make a dust proof and wind tight joint therefor.

This invention comprises an improvement upon the matter of my prior application Serial No. 606,366, filed February 3, 1911, for a window sash, in which aredescribed divided window stiles, which are longitudinally grooved on the meeting faces, and are provided with sheet metal strips secured at the edges in such a manner as to leave free spring edges which overlap as the sash is revolved and abut against the edges of the grooves when the sash is raised to the vertical position.

In the improved form hereinafter described the spring strips are similarly secured over the grooves and are laid over each other at the pivotal point so that they are continuously in the overlapping position throughout their movement although for convenience in manufacture each strip is preferably formed in two sections, the line of separation joint being positioned at the pivotal point.

Other features of the invention comprise means for providing greater freedom of movement for each revolving sash to pass the ends of the runner or sliding rail members of the other sash.

The invention also consists in the combination and arrangement of the various parts and construction of details as hereinafter described, shown in the accompanying drawings and specifically pointed out in the claims.

In the accompanying drawings Figure 1 is a perspective view of the revolving windows showing also part of the sliding stile portions or runners; Fig. 2 is a front elevation of one side of the window showing the respective adjoining outer edges of the upper and lower sashes cut away to permit free action thereof; Fig. 2 is a similar view showing tapering side stiles for the sash; Fig. 3 isa perspective view of the outer edges of the crossing portion of a sliding stile and a revolving stile pivoted thereto; Fig. 4 is a similar view of the inner edges of the same stiles; Fig. 5 is atransverse section of the two stiles at a point removed from the pivot point; Fig. 6 is an enlarged transverse section thereof; Fig. 7 is a perspective view of the inner face of one stile and Fig. 8 is a similar view of the inner face of the stile which is pivoted thereto.

In these views 1, 1 are the side rails of the upper and lower sashes which slide in the ordinary manner in the window frame between stops 2, 2. These stiles are longitudinally divided at 3, 3, and the inner portions 4, 4, are pivoted at 5, 5, to the sliding portions and the window frame is composed of the inner stile portions 4, 4 and upper and lower bars 6 and 7 in the usual manner. The pivots are preferably formed. of straight thin screws 5 as shown in dotted lines in Fig. 6 so as to obtain as great a hold on the stiles as possible.

Each stile portion 1 and 4 is longitudinally grooved on its inner face. The grooves 8 are formed in the sliding stile portions and the grooves 9 are formed in the pivoted stile portions.

To the stile 1 are secured the spring sheet metal strips 10, 11. The upper spring strip is secured at its outer longitudinal edge by nails or screws 12, 12 to the outer edges of its stile, and extends over the groove 8 therein, its inner edge 15 coinciding with the inner edge 13 of the groove. The lower spring strip 11 is secured along its inner edge to the inner edge of the stile by screws or nails 11 and extends over the groove 8 until its outer edge 16 coincides with the outer edge 17 of the groove.

nails 19. That is, the inner edge of the upper strip 19 is attached to the inner edge of the pivoted stile and the outer edge of the lower strip is attached by screws or nails 20 to the outer edge of the pivoted stile.

The 'free edges and 31 of the strips 19 and 20 extend over the groove 9.

The inner extremities of these-strips pref erably overlap at 21, 22 respectively, and the .pivot screw passes through them. These extremities being free can readily be passed underneath the extremities 18 of the other strips and hence the strips on one stile will always be in interlocking position with the strips on the other stile.

When the window is revolved to the ver tical position the spring metal strips still in .terlock and each spring strip will be forced into the-groove in the opposite stile, and the free vertical edge of each strip will engage the corresponding edge of the groove on the adjacent stile it enters, which thus forms a stop to prevent the window from being revolved past the vertical position as shown in Figs. 5 and 6.

In Fig. 2 the edges E and F of the upper and lower sashes are cut away so as to readily pass the sliding strips of the respective sashes when the sashes are lowered and whlch otherwise might lnterfere with each other.

claim as new and desire to secure by Let- I-Iaving described the invention what I ters Patent is:

1. In a pivoted window, the combination with longitudinally divided side stiles, comprising outer sliding portions and inner portions pivoted to the sliding portions, said portions provided with longitudinal grooves on their opposed faces, of spring metal. strips secured to said faces one above and one below said pivotal point, the strips on ,each face adapted to extend over said groove, with their respective lnner edges coinciding respectively with the inner and outer edges of said groove, said strips on the sliding portions above said pivotal points secured to said sliding portions, on their outer edges, and the strips on the sliding portions below the pivotal points secured thereto'on theirinner edges, and the strips on the pivoted portions reversely arranged, whereby the spring strips on one portion are inserted in the groove underneath the strips on the other portion and exert a spring action thereon, the double thickness of overlapping spring strips being retained in said groove,
